FIREPROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 681,105, dated August 20, 1901.

Application led June 15. 1901.

T0 all whom, t may chimera:

Be it known that I, WILLIAM COREY, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements iu Fireproof Safes, of which the following is a specification.

The object of my invention is a fireproof safe the door and door-frames of which will not bulge from the expansion of the reproof filling. This object is attained by the means described in the annexed specification and illustrated in the accompanying drawing, in which the figure is a horizontal cross-section of a safe embodying my invention.

Referring to the parts, outer shell A consists of a front and a rear frame made o f angle-bars a a, to which are secured plates a2, forming the top, bottom, and sides of said shell. To angle-bar ct is secured the casting forming door-jamb B, to the inner edge of which is secured inner shell O. All of these parts are of ordinary construction and need not therefore be more specifically described. Front plate cl, inwardly-proj ectin g castingd, and cap-plate d2 of the door are likewise of ordinary construction.

It has been the custom to fill in the space inclosed by the inner shell, the outer shell, and the door-jamb of the safe and the space upon the interior of the door with iireproof cement. It frequently happens, even though great care be exercised in selecting the cement, that in setting it expands and presses outward in the shell of the safe against the door-jamb and in the door against the inwardly-projecting casting, causing them to swell outward, so that the door binds against its jamb. To obviate this defect, before the cement is applied I place sheets E of material such as sheet metal, asbestos, papier-mch, duc., between the inner and outer shells at a short distance inward from the door-jamb and running substantially parallel to the Serial No. 64,651. (No model.)

sides, top, and bottom, respectively, thereof, securing each sheet by screws or in any other suitable manner at one of its ends to the inner shell and at the other end to the outer shell. Similarly within the door I secure a sheet E parallel to each side of casting d',

leaving a space between it and the casting.

The fireproof cement in its plastic state is then put into the spaces between the outer andthe inner shells of the body of the safe and into the interior of the door, sheets E keeping it back from the jamband from casting d', so as to leave an open space surrounding each, which gives room for any expansion the cement may undergo in setting, so that the jamb and the door are not affected thereby. While this space left about the jamb andthe door overcomes the defect due to expansion of the filling, it does not affect the iireproof character of the safe.

IVhat I claim :is-"

l. A fireproof safe having a space left be tween the cement illing and the door-janib, to allow of an expansion in the cement in setting without affecting the jamb.

2. A fireproof safe within the door of which a space is left between the fireproof filling and the casting forming the periphery, for an eX- pansion in the cement in setting. l

3. In a fireproof safe a sheet of material between and secured to the inner and outer shell thereof adjacent to the door-jamlo and surrounding the same to keep the ireproof filling back from the door-jamb so that the filling in setting may expand without affecting the jamb.

4. A iireproof safe between the door-jamb and lireproof filling of which and within the door of which between the periphery of the door and the ireproof filling spaces are left for the expansion of the filling in setting.

WILLIAM CORRY.
